Hi DRoss. My name is Straight Talk John and I will try to help you. There are phones according to some of our customers confirmed that Windows phone will not really work with the program. The APN Setting we provide will work with phones once you will be able to access your phone's APN Setting and change it. You may need to check with your phone manual or manufacturer on how to locate the APN Settings on your phone. If after changing the APN values on the phone and this still do not work, please try jail breaking the phone and ensure to set the APN values. Thanks!
